TRUSS.

SPECIFICATION forming part of Letters Patent No. 228,981, dated June 22, 1880.

Application filed January 30, 1880. i

To all whom it may concern:

Be it known that I, ADOLPH CHAIM, of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Hernia-Trusses, of which the following is a specification.

The object of my invention is to construct a truss that will allow a slight limited oscillating movement of the pad, following the move- IO ments of the body, while acting upon therupture with an even pressure, the strength of which is easily regulated in a simple and durable manner. Further, to construct and arrange all parts in such a manner as to make the self-same" parts answer for right or left side trusses.

In the drawings forming part of this specification, Figure 1 shows a general view of the improved truss without trimming or other bandage. Fig.2 shows the pad-plate inverted,

2o exhibiting the stem with spring, 850.

shows a section through pad-plate to line as m. Fig. 4 shows a section through pad-plate to line y Fig. 5 shows the pad-stem with coupling detached. Fig. 6 shows the face of 2 5 coupling-gear.

Like letters of reference indicate like parts.

The body-spring A is made in the usual manner. To this the pad-link Bis fastened by two screws, 11 1), allowing an adjustmentin 0 the length of the body-spring. At the other end of the link B a central hole, 0, and a circular slot, d, are arranged, as shown in Fig. 1.

On the pad O rests the pad-plate D, which,

forming a semi-cylindrical shell, incloses the 3 5 pad-stem E, the other half of the cylinder, in

which the pad-stem rests, being recessed in the pad proper, G. On the square portion of this stem, inside the shell, is mounted a spring, G,

preferably made of an ordinary watchspring,

40 which rests with its other free end, g, on the inner face of the plate D, as shown in Figs. 2

and 3. This spring has the tendency to twist the plate with pad 0 on the axis of stem E when the latter is held stationary. At the 5 end of the stem E a stop-screw, H, is tapped,

which, protruding through a segmental slot,

h, in the shell, limits the oscillatory movement of the same. It also serves to hold the Fig. 3

stem in proper position inside the shell of plate D, as shown in Figs. 1, 2, and 4.

The supplementary stem F, which is coupled to the pad-stem E in a manner hereinafter described, forms the connection between the padstem and the pad-link B. A short pin on this partF enters the central hole, 0, and a screw, 6, entering through the slot at, firmly holds the stem at any position, as may be required by the location of the rupture.

The connection between the pad-stem E and the supplementarystem F is formed by two small coupling-plates, which are held together in the center by means of a screw, 2'. The faces of these plates, Fig. 6, are provided with radial zigzag projections or triangular teeth, f, so that the projection onone plate fits into the respective recesses on the other plate. Thus the stem E may be turned in its axis, and the pad may be set at any desired angle in regard to the body-spring, thereby regulating the strength of pressure upon the rupture.

The drawing in Fig. 1 shows the truss when applied to right-side ruptures. The spring G is set as shown in Fig. 3, having the tendency to press the lower edge of the pad toward the bod TX set the same truss ready for use for leftside ruptures, it is necessary only to change the line of the stem-axis, as shown at m m in Fig. 1, unscrew the stop-screw H, change the spring G to the other side, as shown at G, and turn the pad-stem to fasten the stopscrew from the other side. This action will set all parts in position for left-side ruptures without changing the form of any of them.

I am well aware that trusses with an oscillating movement of the pad have been made before. These are provided with a screw spiral spring, and, to my knowledge, have not been made so as to answer for right or left side ruptures without exchanging several parts made especially for such purpose.

I further lay particular stress in the construction of the coupling between the two stem parts E and F, whereby I am enabled to regulate and control the position of the pad and amount of pressure upon the rupture.

What I claim as my invention, and desire shown and described, whereby the same parts to secure by Letters Patent, ismay be reversed and used for right or left In hernia-trusses, the pad-link B, with its side trusses. segmental circular slot d, in combination with ADOLPH CHAIM. 5 pad 0, plate D, stems E and F, and their cog- Witnesses:

connection, reversible spring G, and stop- FRANCIS PEANE, screw H operating in slot h, all arranged as FRANK A. REIKER.
